DIVERASAVING APPARATUS.

Application filed January 8, 1915.

To all whom it may concern Be it known that 1, CHARLES CHRISTIAN- SEN, a citizen of the German Empire, residing at Gelsenkirchen, in the Kingdom of Prussia, German Empire, have invented new and useful Improvements in Diver-Saving Apparatus, of which the following is a specification.

My invention relates to diver savers z. e. to life saving apparatus for divers or for the crews of ships, etc., which enable persons to remain under water for a considerable period. A special application of the invention consists in providing apparatus which enables the crew of a sunken submarine boat to leave their vessel and to move freely when they reach the surface of the water. Apparatus of this kind consist of a buoyant vest and a special breathing equipment or apparatus to enable the wearer to breathe under water. In diver savers of this kind it is important that the breathing apparatus shall be easy to put on and to take off, a. 6. it must be easy to attach to and to detach from the buoyant vest that envelops the body of the wearer. It is of special importance that the detaching of the apparatus may be easily and quickly executed as the wearer of the diver saver must be able to perform these acts in the water when he has reached the surface. The known apparatus of this kind require a large number of manual acts to be performed by the wearer in order to divest himself of the breathing apparatus.

The object of my invention is to simplify the manual operations and to provide a highly practical and effective diver saver.

According to my invention the connection between the buoyant vest and the breathing apparatus is of such a nature that it can never accidentally become undone and that its parts are securely held in their relative positions, but that in spite of this only a single manual act need be performed by the wearer in order to dissolve the connection of the said parts so that only the buoyant vest remains on this body while the breathing apparatus is detached.

My invention is illustrated by way of example in the accompanying drawing.

Figure 1 represents a front view of the buoyant vest; Fig. 2 is a front view of the breathing apparatus; Fig. 3 is a view corresponding to Fig. 1 of the buoyant vest with the breathing apparatus fastened thereon;

Specification of Letters Patent.

Fig. 4 is a side view of Fig. 3 showing a section on the line AB.

a is a feed gas flask containing oxygen sub ected to a high pressure which is fed into a breathing bag. b is a regenerator which absorbs the carbonic acid of the air explred by the wearer, o is the breathing bag which renders possible and regulates the breathing of the wearer, cl is an automatic regulator that regulates the flow and pressure of the feed gas from the flask a. These well known parts are all fixed together; they form the working portion of the breathing apparatus.

n and 0, Fig. 2 are flexible pipes which connect a mouth piece p, Fig. 2, t0 the breathing bag a. The wearer puts the mouth plece p in his mouth in the well known manner, the mouth piece being made of rubber. The pipe at furnishes the wearer fresh air which he inhales, while 0 leads off the used air which is conducted to the regenerator 6. Three loops 7, g and g are fixed to the breathing apparatus. It will be seen from Fig. 3 that the loop f fits in between the loops 7 and f and the loop 9 fits in between the loops 9 and 9 A strap or band is fixed to the lower part of the breathing apparatus, this strap being passed through a loop m at the lower portion of the buoyant vest Z so as to attach the breathing apparatus to the vest. The free end of the strap is formed in the shape of a loop 2'. A rod is is slipped through the loops 7, f F, a, g g 9 The breathing apparatus will then be securely fixed by connecting points situated in the three corners of triangle to the buoyant vest. Two corners of the triangle will be at the upper portion and the third corner at the lower part of the vest. Since the weight of the breathing apparatus is entirely or almost entirely compensated by the buoyancy of the buoyant vest, the rod may be readily pulled out of the previously mentioned loop while the wearer is in the water.

When the wearer reaches the surface of the water and Wishes to divest himself of the breathing apparatus, he only needs to catch hold of the handle of the rod is with one hand and to pull it out of the loops. The breathing apparatus then readily falls down, so that the strap is prevented from being caught at any part of the vest. A complete separation is thus insured and all danger for the wearer is removed;

I claim:

1. In a life saving device comprising two parts, the one part being a buoyant vest and the other a breathing apparatus, a detachable connection between'the said buoyant vest and the said breathing apparatus, said connection consisting of loops at the upper part of the buoyant vest, loops at the upper part of the said breathing apparatus adapted to fit in between the said loops on the buoyant vest, a strap whose one end is attached to one part of the life saving device and a part of which is passed around the lower part of the other part of the life saving device, a loop at the other end of the said strap'and a rod which is passed through the said loops of the buoyant vest, breathing apparatus and strap and which may be pulled out thereof.

2. In a life saving device comprising a buoyant vest and a breathing'apparatus, a detachable connection between the said buoyant vest and the said breathing apparatus, said connection consisting of loops at the upper part of the buoyant vest, loops at the upper part of the said breathing apparatus adapted to fitin between the said loops on the buoyant vest, a strap whose one end is attached to the breathing apparatus, parts at the lower portion of the buoyant vest around which the strap is passed, a loop at the other end of the strap adapted to fit in between the said loops and a rod which is passed through the said loops of the buoyant vest, breathing apparatus and strap and which may be pulled out thereof.

3. In a life saving device comprising a buoyant vest and a breathing apparatus, a

detachable connection between the said buoyant vest and the said breathing apparatus, said connection consisting of loops at the upper part of the buoyant vest, loops at the upper part of the said breathing apparatus adapted to fit in between the said loops on the buoyant vest, a strap whose one end is attachedto the breathing apparatus,

a loop at the lower end of the buoyant vest through which the strap is threaded, a loop at the other end of the strap adapted to fit in between the said loops and a rod which is passed through the said loops of the buoyant vest, breathing apparatus and strap and which may be pulled out thereof.

4:. In a life saving device comprising a buoyant vest and a breathing apparatus, a detachable connection between the said buoyant vest and the said breathing apparatus, said connection consisting of loops at the upper part of the buoyant vest, loops at the upper part of the said breathing apparatus adapted to fit in between the said loops on the buoyant vest, a strap whose one end is attached to the lower end of the back of the breathing apparatus, a loop at the lower end of the buoyant vest through which the strap is looselypassed from below, a loop at the other end of the said strap and a rod which is passed through the said loops of the buoyant vest, breathing apparatus and strap and which may be pulled out thereof.

In witness whereof I have hereunto-set my hand in presence of two witnesses.
